STC Astro-Multispectra Clip Filter for Nikon APS-C bodies is a novel light pollution filter designed by STC Optics with transmission characteristics designed by professional astronomer and renowned astrophotographer Dr. Wei-Hao Wang.
- Significantly reduce light pollution from artificial lighting in city
- Allows the use of much wider lens when compared with front mounted filter
- Easily install or remove for Nikon APS-C cameras
- Natural colour representation
- High transmission for astronomical bodies emission
- Easy to clean thanks to anti-static and greaseproof coating
- Co-developed by STC and Dr. Wei-Hao Wang, a professional astronomer and renowned astrophotographer
|The beautiful M42 Great Orion Nebula on the cover was captured by Mr. Szeto under the serious light pollution in central business district area located in Hong Kong, which is a well known severely light polluted city in the world. With the effective light pollution suppression through this newly launched STC filter, the details instantly pop out against the background.|
^Due to the differences in optical design among various lenses, when used with some fish-eye lens, ultra wide and wide angle lenses, the corners of the image might appear softer which is a normal optical phenomenon

Placing the light pollution filter closer to the sensor reduces color shift that may occur at the peripheral areas of the image if front screw-in lens filter is used. STC recommends using STC Astro MS Clip Filter for Nikon-APS-C with SLR lenses of focal length 14mm or longer, and avoiding directly taking pictures to strong artificial light which may cause slight flare on image.

STC Astro-M Transmission Characteristics
- Natural colour representation by selectively blocking out UV light below 410nm, sky glow in between 620nm and 640nm and infrared light beyond 680nm
- High transmission for astronomical bodies emission at Hα=656.3 nm, Hβ=486.1 nm, OIII=495.9 & 500.7 nm, SII=672.4 nm and slightly passing yellow-orangish emission at 605nm.
A. Remove the lens from the camera.
B. Insert the Astro-MS clip filter into the camera.
C. Press the clip filter firmly into place
D. Attach the camera lens and start shooting!
STC utilises ion beam assisted deposition (IBAD) to solidly bind the coatings onto Schott B270 glass, the very same glass used in Zeiss lenses. Such technique enhances the light transmission and also durability of the 160 layers of coating deposited to produce the advanced filter characteristics shown above.
With patented Ultra Layer® technology, both surfaces of Astro-Multispectra are coated with Anti-Smudge nano-coating to prevent dust and water from settling on the filter surface. Dew will not form and your filter is always clean. If necessary, it's effortless to clean.
